This is the same Larry Wood-designed Porsche 928 casting.
Model 5180 corresponds to its 1982 release in "The Hot Ones" series, which featured GHO (Gold Hot Ones) wheels.
This "Hot Ones" version is notable for its speed on the track, thanks to the low-friction GHO wheels. It was typically released in a metallic gold color with red and orange graphics, matching the gold color of the wheels.
This is a specific release variation of the P-928, distinct from the mainline and "Real Riders" versions due to its wheel type and paint scheme.
"The Hot Ones" release is a key special edition. The mainline and Real Riders versions from the same era offered different wheels and colors.
